This place is a cut above the rest. All of the staff is super helpful and very professional.The professionalism is second to none.You can tell they love working together by the energy and optimistic attitude shared by everyone in the shop.Cant wait to come back and do more business.

I entrusted my 2020 mid engine C8 Corvette to GRP for an exhaust install. The process was seamless. They ordered the Lingenfelter exhaust through their outsourcing and it was dropped shipped to their shop. Once in, I got a call from Alex Sweet and my installation was scheduled.I have to say they got my car done perfectly! They ensured everything was the way it should be before returning it to me. They too have the mentality you that I have, and that’s ‘measure twice and cut once’ mindset.I’m extremely happy with their work, their installers and the shop is a clean and pristine environment!I also might add, prior to the process I was invited out to hear the exhaust I was considering on another C8 Corvette and once my mind was locked and loaded on the modification, Alex went over the cost, terms, paperwork, deposit as well as expectation on delivery and the product. When my car was delivered Alex went over the changes and I couldn’t be happier!I’ve already expressed yet another part install in the near future to this car and only GRP will be allowed to handle it for me.I’ve also talked to Ken Lingenfelter personally about this current modification that bears his name as well as the future part that I’d like to have installed which is sold by his company LPE.I’d like to personally express my thanks to Graham Rahal for taking the time out to personally talk to me about the performance exhaust I wanted, putting me in touch with GM Keith Gingerich who knew what I was contemplating after conversation with Graham, Alex Sweet who’s in charge of Service and Josh McGaughey in Parts. The entire shop and technicians all deserve kudos for what they do.

Great job! Enjoyed everything and they really made the effort to include the kids!Always look forward to it.

Coming here was definitely worth the traffic..I seen some smoking Ducatis to jaw dropping you dont see every day Porsche, custom dodge ram truck. If your in Indianapolis... go here, the staff is amazingly friendly and can answer any questions lol. Everything is for sale

I visited to have the exhaust upgraded on my Acura RDX. Gotta tell ya Graham and his staff are awesome. Drove up from TN and arrived earlier than expected. They were able to get started early and finished up in no time at all. Ill definitely be back for more upgrades.

Where do I begin. Top notch personal. Greeted right away, provide excellent recommendations and service. Instantly was AMAZED in the end result. My Audi S8 will never be the same. Thanks Jared and Team!!!

A big thank you to the management of Rahal performance. The cruising with a huge success. Thank you for hosting it.

The staff were very knowledgeable and helpful. A great group of guys. They have a large inventory as well. My next toy purchase will definitely be from them.

Great company. Helpful employees. 10/10

Im new to BMW ownership and GRP does BMW stuff, so I stopped by to get some info. Very nice, professional people...Austin listened and gave me some very good info. I didnt catch the receptionists name, but she is the perfect person to greet and direct potential customers to the right associate. Now to decide just what I may have done to my Baby BM-er.Decisions, decisions...

Great group of car enthusiast! Top notch facility!

Outstanding work! Austin Brown was great to work with and very knowledgeable. Great service and pricing!

It was great lot of cars showed up an the display of there vehicles was the same

Very cool place, motorsports enthusiasts are always nice to meet.

Rahals facility out here in Brownsburg can be summed up in one word: clean! The shop and all of the bays are exceptionally clean. Their stock of vehicles for sale, as well as the historical value of them is not to be downplayed. I would not hesitate to take my vehicle here for some much needed upgrades. I look forward to coming back out for the next cars and coffee event here!

Great customer service thanks for the dyno services will be back for more testing!!

Jarrad was great to work with- professional, knowledgeable, and was able to source some hard to find wheels for my Civic Type R. You wont find a shop more passionate and dedicated than GRP!

Great shop. Great guys. Extremely knowledgeable. Highly recommended.

Bought a car from Graham and GRP and could not be more thrilled. Graham and his team went out of their way to ensure it was a smooth and seamless transaction. As the car I purchased is a very rare model and specification, I was incredibly happy with the extra attention they paid in inspecting, taking care of, as well as delivering my car. I am walking away excited to do business again with Graham and his team and highly recommend GRP to everyone.

These guys are trust worthy and great to deal with

Jill is awesome. We reached out from California to inquire about a Porsche they have listed.Jill patiently answered all of our questions and even sent several pictures of the car. It’s always nerve-racking inquiring about a car out of state but Joe made the entire process very comfortable for us.

GRP is an awesome shop and provided one of the best performance shop visits I have had! Austin is very good at communicating with you during your experience there and the entire GRP staff and shop are top level. Had my C6Z retuned by Griff and I can not be happier, he dialed in my pervious tune and the car now runs better than ever, appreciate your skill and time Griff! Thanks again to everyone at GRP, you may get tired of seeing me in the future!!!!!!!

We are working through the issue now and the problem has been solved and was no fault of GRM. Austin and the tuner went over and above re- checking my Tune, and it ended up being an exhaust issue. I wish i knew how to delete my bad review. I was just frustrated!! Good Job guys😁🏁

Everything that leaves this shop is incredible. The quality is amazing and jaw dropping! Social media posts stops the scrolling because you have to take a look of what incredible work has been done. Give the Facebook page a like. You wont be disappointed!

Top notch! Thanks Graham and Jarred for an easy transaction (sight unseen). These guys are professionals and trustworthy. Will be back...

Always a pleasure to deal with. Lots of expertise and fair prices. Jarrad will make sure things get done right!

Great customer service and a shop run by true automotive enthusiasts! I will definitely be using GRP again in the future.

Super nice staff and perfect service.
